Failed to renew certificate

For about a week I’ve had no access to my gateway via https://xxx.mozilla-iot.org/ but I do have local access. I get the following in my log file:

2020-05-24 13:42:04.245 ERROR : Failed to renew certificate:
Error: Error creating new order :: too many certificates already issued for exact set of domains: xxx.mozilla-iot.org: see https://letsencrypt.org/docs/rate-limits/
at AcmeApi.apiRequest (/home/pi/mozilla-iot/gateway/node_modules/acme-client/src/api.js:54:19)
at process._tickCallback (internal/process/next_tick.js:68:7)

I see a similar post for a docker user that doesn’t seem to offer appropriate help. The rate-limits page from letsencrypt provides some hints but I’d sure rather not wait a week to renew, particularly if something else is going on that causes a renewal failure to begin with. Anybody have a suggested path forward? I’m using a Rpi4 that’s been trouble free since implementing in September. I’d sure like to get it back up and working for me.

Thanks in advance.

If you look through your other (older) log files, do you see any other errors occurring when the gateway tries to renew the certificate?

This problem is on me. The router firewall was over-constrained up until a few days ago, interrupting the renewal process.

The cert reissued today so the problem is fixed. Prior to today (for several days) I was getting the same “too many certificates already issued” in the log files. Before that for about a week I was getting a renewal failure with “ETIMEOUT 172.65.32.248:443”. Bottom line is my firewall was not allowing the traffic.

Thanks for your time. Hopefully my issue can help someone else out in the future. Lessons learned where 1) read the log files and 2) the gateway must communicate with more than just the AWS server at 52.25.215.5.
